DOOR-OPERATING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 749,108, dated. January5, 1904.

l pplication filed March 11, 1903.

To all whom, it 1nay concern.-

Be-it known that I, LOUIS A. SHEPARD, a citizen of the United States anda resident of the borough of Brooklyn, city of New York,

State of New York, haveinvented certain new and useful Improvements inDoor-Operating Mechanism, of which thefollowing is a specification. 7

My invention has for its object the provision of an improveddoor-operating mechanism for railway-cars which is characterized bylightness and ease of operation and at the same time by the greatstrength and power with which it holds the doors in a closed position.It furthermore provides an improved fulcrum by which the toggle arm orlink may be united to the operating-beam of the doors, which fulcrum iscapable of being readilyremoved or detached from the said beam.

The scope of the invention is defined by the appended claims.

In the drawings .which accompany this specification, Figure'l is abroken plan View illustrating my invention, together with a portion of acar-frame and the doors to which it is applied- Fig.2 is a section online 2 2 of Fig. 1, showing in addition certain adjacent parts of thecar which are omitted from Fig.

:1; Fig. 3 is a. transverse vertical section taken through the axis ofthe toggle-joint. Fig. 4 is a detailview showing a bottom plan of thetoggle-joint; Fig. 5 is a detail plan view showing the fulcrumpreferablyused by me, together with portions of the door-operating beam. andtoggle-arm. Figs. 6, 7, and 9 are enlarged top,side,and end views,respectively, of the fulcrum of Fig. 5. Fig. 8 is a sec tional view of amodified form of fulcrum, and Fig. 10 is an end view of one of themembers of the said modification. I

The door-operating mechanism is preferably to be used in the operationof the doors used in railway-cars for the carriage of coal and othermaterials which are self-discharging.- Such doors are often arranged inpairs 1 1 and may be operated by a single beam 3, as shown in Fig. 3.Furthermore, opposing pairsof doors may be operated by a singlemechanism, as the doors 1 and 2r (Shown in Figs. 1 and 2.) v

'Myinvention when the doors are arranged in pairs comprises theoperatingbeams? 3,

.tance from the said axis or pin 8.

which are rigidly securedat each end to the as shown in Figs. 1 and2,-or it may be com-- posed oftwo or more parts secured together and tothe beam 3, as the fulcrums of Figs.

5 to 9 or as the fulcrum shown and claimed thereby drawing .the beams 3toward each other and opening the doors. The said means may be of anyapproved construction, such as a link 7, connected at its lower end tothe pin 8, forming the axis of the togglejoint, andat its upperend'connected to an arm 9, fixed upon thehorizontal shaft 10.

'The said shaft is preferably jou-rnaled in bearings 11 and;l2,supported by the center sill l3 and side wall 14 of the car, as shown inFig. 1. One end of the said shaft carries a notched plate 15, adapted tobe engaged by the'locking-dog 16, and thereby firmly held.

In order to keepmhe axis 8 of the togglejoint in a vertical path whenraised by the arm 9 and link 7, I provide each of .thetoggle-arms with alaterally-extending lug or projection 18, which is situatedat some dis-Ve rtical guides are provided for the said lugs and may consist ofangle-beams 19, as shown. In

place of the. said beams, however,I may substitute therefor channels, orinstead of using a single angle, as shown, a pair ofangles may be used,between which the lugs 'may operate. It is obvious that any other formoi vertical guide may be used, however.

It is evident that in case single doors'l and Correction in LettersPatent No. 749,108-

What I claim,an'd'desire to secure by 2 are arranged opposite eachoth'er the beams 3 may be dispensed with and ihe toggle-arms 6 applieddirectly to the doors.

The fulcrum illustrated in Figs. 5, 6, 7, and 9 is composed of twosimilar complementary pieces or members 21 22, each of which carries ajaw 23, which together form the fork to which the toggle-arm is to, be.secured. The ends of the pieces 21 22 opposite the jaws 23 terminate inthe flattened end portions 24, which are perforatedand adapted to beclamped by a rivet or other suitable means against opposite'faces of theweb of the. flanged bea|n3.; The intermedi ate or body portions'oft-hemembers 21 and 22 are so shaped as to-providedeep grooves or recesses26, which receive the flanges of the I-beam3, These portions are alsoprovided with sloping'shouldersior angular projections 27.27, whichabut"and interlock when'the members 21"and 22 are brought' together.

Each of the'j-aws 23 is provided with a perforated" boss 28. Thesebosses occupy similar relative positions with respect to thejaws,andwhen the members 21and 22 are brought together the bosses 28 abut.against eachother and may be secured in this position by a rive't orbolt29 passing through their centers, as best seen. in'Fig. 6. The jaws23'are also bored with pin-holes ,30 for the purpose of securing thetoggle-arm'theretm By this con struct-ionwhen the mem'bers'2l and 22 arefitted togetheraround the flanges of the beam 3 and therivetsinsertedaveryfirm and rigid union of parts is secured.

the shoulder 32 bears against the opposite jaw 23', while the shank'33passes through an aperturein the latter jaw and may be riveted, as shownin'Fig -S; L I
